STATIONERY.

Specication of Letters Patent. Patented NOV. 16, 1920.

Application filed October 4, 1919. Serial No. Y 328,568.

' To all whom 'it may concern:

Be it known that I, A1z1s'rn)ns CALoAo, a citizen of Venezuela, and resident of La Guaira, Venezuela, have invented Certain new and useful Improvements in Stationery, of which the following' is a specification.

My invention is an improvement in stationery, and has for its object to provide a combined envelop and inclosure, formed from a single blank having lines of partial separation and lines of adhesive for permitting the sheet to be folded into a letter` and an envelop for the letter.

In the drawings:

Figure 1 is a plan view of one of the blanks;

Fig. 2 is a similar view showing the letter folded;

Fig. 3 is a plan view, showing the envelop folded, with the exception of the seal flap;

Fig. 4 is a similar view with the envelop completely folded, stamped and ready for transmission.

In the embodiment of the invention shown, a pad is provided, consisting of a number of similar sheets 13, the said sheets being arranged one upon the other," and they may be connected at one end by an adhesive in the usual manner. rlfhe sheet 13 is partially divided by alined lines of partial separation 14 and 15, extending transversely of the sheet approximately one-third the distance from the upper end, and these lines of partial separation extend inwardly from each edge, being formed by perforations or in any other suitable or desired manner. The line 14 of Vpartial separation is about one-half the length of the line 15, which is the same length as the distance between the adjacent ends of the lines 14 and 15.

The arrangement is. such that when that portion of the sheet below the line of partial separation 15 is separated and folded over uponthe remainder of the sheet, the free edge of the said portion will be flush with the inner end of the line 14. A third line of partial separation 16 is provided, extending from the line 15 to the top of the sheet, parallel with the side edges of the sheet, and at a predetermined distance from the adjacent edge.

Taking the sheet shown in Fig. 1, which has a width of three and three-quarter inches, which may be considered as fifteen quarter inches, and taking the quarter inch as a unit, the line 14 will have three units, the line 15 six units 'and the` distance between the lines 14 and 15 six units.

The line 16 is spaced from the adjacent edge a distance of two units. Y

In use, the letter is written on thatV por tion of the sheet below the lines 14--15, and the full width of the sheet may be used, or merely that space comprised between the vertical lines dropped from the adjacent ends of the lines 14-15 of partial separation. The letter may be written on the typewriter or by hand, as may be desired, and it will be evident that there is nothing to prevent the insertion of the sheet in a typewriting machine in the usual manner. After the letter is written that portion of the sheet containing the letter and below the lines 14--15 is separated from the right hand edge to the inner end of the line 15, to form a liap which is folded smoothly over on to the body.

Now that portion of the sheet below the line 14 is separated to form a flap which is folded smoothly over upon the first named flap. The bottom half of the folded portion is now doubled over upon the upper half, as indicated in Fig. 2. That portion of the sheet above the line 14 of partial separation is provided at the adjacent side edge with a line of adhesive 17 for sealing the inclosure in a manner to be presently described. In addition to the lines of partial separation 14-15-16 that portion of the sheet outside of the line 16 is provided with two lines of partial separation 18, which converge from the line of partial separation 16 to the free edge of the sheet.

It will be evident that when the sheet is separated on these lines 18 a tongue 19 will be formed. Just inside the line 16 a vertical slot 2O is provided, and another slot 21 is arranged in the line of adhesive, the Y and itwillbe notioed thatzthslline Kis just below the outer edge of the sealingflap '9 when the said flap is folded.

I claim:

A combined letter sheet and envelop comprising a rectangular blank having lines-'of partial separation extending from its oppo- .site edges `'toward -`the f center `at flapproximately one-third the distance .from one end, one of said lines being of greater length than ythe other and the `sheet beingadapted toloe separated fat' thesaid: lines andv to' have its Asideedges"folded over iipoIreaoh-other7 with the wide side edge beneathf the narrow side-edge '.andthe'n 'to be doubled Vtransversel'y :and folded onto fthe remainder of the"heet5'the-reinaini1ig portion of the sheet 'having' at one side edge a line of adhesive fandvtheaid side--edgesbeing adapted to be folded over upon each other over the folded "vfletter sheet to form the envelop, with the to dene a" tongue 'in'seitible 'outwardly' through the slot" in thesealing 'fiapj'and nwardlyzthrough the- Slot inf the back iiap. t
